[LOOKING FOR A FIX] DATA drops

Thank you for this investigation! I got those data drops/delays you are taking about. I did cut my SIM to a micro myself and it's far from a perfect match in the sim tray. I'll go to my carrier and get a new one today. Will report back later.

I get wifi drops! So when I turn on my phone after a long period of time (like night) the wifi bar is grey, indicating that no more connection there is. After 30 seconds or so, it turns blue again. What is happening

I have been have issues with my nexus 4 here in Massachusetts with t mobile where i get "H" showing up on my signal but for no reason it switches to "E". The signal strength is good so i think it is just randomly dropping the data signal. The most annoying part of all of this is that my blackberry holds a solid 4g connection sitting right next to my n4, even with the same sim card.

I have the exact same issue, as soon as I use any app that requires data connection it will disappear for a few seconds, long enough most of the time to have the app or page to time out. I am still on stock everything, hesitant to try anything so far.

I do use WIFI extensively, one thing I have noticed though, rebooting the phone every other day somehow helps,

I am on TMO in houston metro area. There are some dark spots on TMO network all around houston, I also tried the fast tmo (TMO LTE?) apn and did have some success with that.

I have seen posts elsewhere that a replacement device was required to fix the issue, anyone got a replacement device that completely eliminated this issue?

I blame TMO most of the time though not the phone, I had similar troubles (much worse) on my SGS4g as well.

It seems to be working decent without the LTE/GSM/CDMA thing, but it's very slow and it seems quite laggy (enough laggy for facebook messenger to time-out). Switching to that from WCDMA drastically improves speed and responsiveness of the network. Mobile websites are loading within 1 second (feels almost like on wifi). I don't know if it's the combination between ROM, kernel and that setting for network or something else.

But I can say that I was getting serious drops on Montley kernel. On franco kernel, the mobile data was completely unusable (it was just staying on grey H, never switched to blue H/H+ or loaded anything).
